Safari update 14.0.1 issue uploading files

Yes, the Apple Support person determined the drag & drop worked but not the "attach" button. That was why she said that Finder had somehow be one "disconnected" to Safari and determined that Mojave needed to be restored.

Confirmed

re-installing Mojave’s last version (10.14.6) puts you back to Safari 12.1.2

i can’t think of any mind blowing updates to Safari in 13 or 14 so I didn’t bother updating the browser - someone care to refresh my memory on what I might be missing out on?

everything that I noticed was broken before with Safari 14.0.1 was now functioning again with JUST the restore of Mojave

I also can't attach files using the attachment button in either Gmail or Yahoo mail. I'm running Safari 14.0.1 on macOS 14.0.6. It clearly appears to be a Safari 14.0.1 problem. I have no problems when I use Chrome or FireFox. Unless Apple fixes this, many of us will have no further use for Safari.

I reinstalled Mojave and added the security update but *not* 14.0.1. And uploading works in Safari and Chrome and Brave for me. And uploading worked in Brave and Chrome before I reinstalled. I think it's a Safari issue.

Same problem here, using Safari Versión 14.0.1 (14610.2.11.51.10) and Mojave Version 10.14.6 (18G6042). Upload button broken in every site. Forced to use firefox instead as a workaround while waiting for the bug to be solved.

Yes it is Safari 14.0.1 issue in Mojave - logged multiple times with Apple.

See my post under Safari - just posted entitled

ANSWER - method to downgrade from Safari 14.0.1/Mojave (multiple problems eg loading files)

It was frustrating reentering all my passwords into Chrome, but yes Chrome works totally fine. I would assume many apple developers and employees are suffering from the same problem. It's hard to understand how they could let this remain unresolved for so long.

1. This problem is solved by going to the website you want to got.
2. Go to Safari Menu File
3. Select Preferences for this website
4. Deactivate „Inhaltsblocker“ aktivieren (secon from top)

Because my Mac is in german language you have to translate.

The only way I could get this to work was to install Catalina. My mac is older so it worked. Now can upload & download.

Same issue, definitely frustrating, but technology happens. I switched over to chrome. I did read it seams to be a Mojave specific issue.

I have the same problem but have found that I can still drag and drop files wherever it is that I need to upload them. It's not convenient but it works.

Mojave user here (can't upgrade my OS any further on my 2009 Mac Pro) so just dragging & dropping as a workaround till a fix with Safari comes.

Had apple support do screen share to see that "attach" does not display file directory (to select from) when using Safari but does work when using Chrome. They have elevated the issue to a higher technician. Waiting until tomorrow for follow call. In meantime am using Chrome as a workaround.

Agreed - but using the procedure outline in this thread, a re-install of the OS really isn't either risky or complicated.

I didn't like the idea - and we all wish it weren't needed.

But its only drawback is time: allow an hour.

It also means that anything else that might have become corrupted or otherwise non-functioning over time will almost certainly be put right. It really does sound worse than it actually is. Good luck!

Yes, like many, same issue. Cannot attach files in gmail; cannot choose files to upload on Canvas, a course management site. Haven't tested other sites.

Mojave 10.14.6; system update or reinstall not feasible or practical.

I was able to drag-drop files into an open gmail to attach. That option is not available on many other websites, however. To attach files on many sites you must use the "choose file" button, which - Apple: Does. Not. Work.
